IMPROVEMENT IN VEHICLE SHIFTING SEATS.

Specication forming part of Letters Patent No. 210,031, dated November19, 1878 5 application iiled October 31,1878.

To all whom it may concern.'

Be it known that I, JOHN A. HAWTHORN, of

. the city of Lancaster, in the county of Lanv and apply the same, inwhich- Figure l is a front elevation of the seat with the appliances andthe supports on the sill. Fi g. 2 is an end view centrally; the solidand dotted lines indicate the position on either side the seat can bemade to assume. Fig. 3 shows perspective illustrations oftheconstruction of the several combinations shown detached.

To the under side of the seat A, near the ends, on each side, is afixedthe upper plate, B, provided with lugs B, forming a double bearing. Asimilar plate, P, is attached to the inner vertical face of the sill Sof thevehicle, with like double bearings lt. The supports or legs O havetheir ends, on opposite sides ofthe saine, provided with an extra lug toiii'J into the aforesaid double bearings B R on the seat andsill-plates, by which the seat is more firmly supported on thepivot-bolts through said double ends and bearings. These legs O arecombined, also, near their upper bearings, by a curved cross-piece, F,to which, at its center, an oblong square lug, E, is affixed iirmly.This lug E projects on the inner side, for the purpose hereinaftermentioned. There is another plate, O, parallel to plate B', under theseat, on each side, having lugs or bearings C, for a hinged archedcatch-plate, D, provided with a notch, d, een trally to receive thesquare edge of the projecting lug or bolt E, aforesaid. On each end ofsaid arched and hinged catch-plate D there is a rigid projectingfootpiece, Gr, upon the upper surface of which a tion to the front orrear of the vehicle.

strong flat spring, H, is made to bear, to hold the hinged arched pieceD firmly against the lug E, that locks or enters the notch d, aforesaid.The one end of these springs H is afxcd to the under side of the seat A.Thus the seat is doubly braced and firmly locked and held in place.

In order to disengage the parts for shifting the seat back or front,Iuse a lever, L, centrally, so as to allowr it to vibrate on a standard,K, connected with a plate attached to the under side of the seat, saidlever being secured by an ordinary nut, N, and washer. It also has rodsM' M, one on each side, as shown, either to pull or push the lever toone side or the other.

m are staples, which support the ends of the rods. To operate the hingedarch-pieces D, I affix an eyed staple, t', to them, from which a wire,I, connects with the forward portion of the lever on one side, and awire, J, on the rear portion of said lever with the like connection onthe other side. Thus it is easily understood that a push or pull on thelever tends to draw both hinged and notched pieces D inward, so as tobecome disengaged from the lock-piece E, and allow the seat and combinedlegs to lie or fold down in either direc- The raising of the seat willlock the same by the spring-action.

The arched piece might be provided with notches at several points, so asto adjust the seat to several different elevations, if desirable.

I am aware th at legs on pivots uniting the seat and sill on plates areshown in various patents,

and that springs, notches, and levers are not i new; nor do Iclaiin suchapart from the construction and combined arrangement herein set forthand described; but I am not aware that legs have heretofore been usedhaving each end adapted for double bearin gs, and combined with an uppercross-piece in pairs, nor that the hinged and notched cross-piece withits projecting feet were ever before known or used in shifting seats.Therefore,

What I deem novel and useful in my ar rangement, and desire to claim asmy inven= tion in jump or shifting seats, is-

1. The crosspiece or brace F, provided with a central lug or piece, E,in combination with the pair of supports O, each end adapted to thedouble bearings on the Seat and sill plates B l), substantially as andfor the purpose specified.

2. In combination with the lug or piece E on brace F, the arched andhinged plate D, having notch d, when provided with a projecting foot orpiece, G, a spring, H, eyed lng i, wires I J, and lever L, the Wholearranged and operating substantially as and for the purpose hereindescribed.
